CS寻呼优先发送功能的实现

Realization of CS Paging Transmission Priority

目前网络模式下,CS业务与PS业务都使用相同的公共控制信道(CCCH)来发送寻呼和信道的立即指派消息,在数据业务非常集中区域,就会出现由于PS业务的大量使用造成CCCH信道资源不足,导致CS寻呼拥塞,本文通过分析CCCH信道的结构和原理,引申出CS优先发送功能的实现机制,通过网络实验分析证明该功能对于解决CS寻呼拥塞起到重要作用。

CS and PS paging or channel assignment message are sent on the same common control channel （CCCH） in the present network mode. When the data traffic is very concentrated in same area, there will inadequate resources of CCCH channel due to a large number of PS message, resulting in CS paging congestion. By analyzing the CCCH channel structure and principle, this paper gives rise to the realization of a mechanism on CS Paging Transmission Priority. By the network experimental analysis, it shows that this function plays an important role for solving CS paging congestion.
